(PHP ActiveX) Get Certificate Valid To/From Dates
Demonstrates how to get the certificate "valid from" and "valid to" dates.
<?php
$cert = new COM("Chilkat_9_5_0.Cert");
$success = $cert->LoadFromFile('qa_data/certs/testCert.cer');
if ($success != 1) {
print $cert->LastErrorText . "\n";
exit;
}
// Get the certificate valid-from date/time
// ckdt is a Chilkat_9_5_0.CkDateTime
$ckdt = $cert->GetValidFromDt();
// Get the local timestamp string.
print 'Valid from: ' . $ckdt->getAsTimestamp(1) . "\n";
// Valid from: 2017-03-17T19:00:00-05:00
// Now get the date/time as another object where we can get the individual numeric date parts.
// dt is a Chilkat_9_5_0.DtObj
$dt = $ckdt->GetDtObj(1);
print $dt->Day . '/' . $dt->Month . '/' . $dt->Year . ' ' . $dt->Hour . ':' . $dt->Minute . "\n";
// Get the certificate valid-to date/time
// ckdt is a Chilkat_9_5_0.CkDateTime
$ckdt = $cert->GetValidToDt();
print 'Valid to: ' . $ckdt->getAsTimestamp(1) . "\n";
// Valid to: 2020-03-18T18:59:59-05:00
// dt is a Chilkat_9_5_0.DtObj
$dt = $ckdt->GetDtObj(1);
print $dt->Day . '/' . $dt->Month . '/' . $dt->Year . ' ' . $dt->Hour . ':' . $dt->Minute . "\n";
